Without argument, Relax Gaming struck gold with its Money Train franchise. The first game in this series debuted in August 2019 and made a splash in the interactive gaming landscape. However, it was not until its sequel was released in September 2020 that this brand became a household name. Money Train 3 was an equally thrilling Wild West ride, and now Relax is claiming that the fourth addition to this series, Money Train 4, will be the last one. Though that should be taken with a grain of salt, as if this title does the gangbuster numbers most expect, it is super likely that Money Train 5 will be on its way.

The gameplay of this sequel takes place on a 6x6 grid, where the scatter-pay mechanic is utilized, and a high volatility math model is in play. The hit frequency here is 20.14%, the RTP stands at 96.10%, and the max win was adjusted to a jaw-dropping 150,000x.

 As you would expect, this game seeks to dazzle with its respins feature and what is now its renowned Money Cart Bonus that carries loads of special feature symbols. If this is really the end of this franchise, then Relax Gaming chose to end this chapter of its history with a bang, as Money Train 4 lives up to the hype and does not disappoint.

Money Train 4 boasts a different setting than its predecessors. Yet, it retains its steam-punk vibe since it expands on the previously created dystopian Mad Max-like universe. We can say that the visuals here are a bit more polished, as they are crisply illustrated images with loads of details that have a 3D look about them. 

The gaming action here takes place on a 6x6 grid where the low-pay tokens are different-colored card suits (clubs, hearts, diamonds, and spades), and the premiums are character symbols. The lowest scatter wins (ten matching ones) awarded in this reel spinner range from x0.4 to x1.2, and the highest, for symbol groups of thirty-six identical tokens, pay x100 to x1,000. Note that there is no wild in Money Train 4, and we think the subtle Western theme nicely complements the base game, and the music in this slot ramps up in its bonus mode, as you would expect.

Know that Money Train 4 is a 100% mobile-optimized spinner featured at the best casino apps. Thus, if you own a newer iOS or Android-powered tablet or smartphone, worry not, as you have the right tool to embark on a neo-retro gaming voyage on this title’s digital reels.

In Money Train 4, your aim is to have groups of ten low-pay symbols appear on the 6x6 grid or two of the top premiums show up because only in those scenarios will this game award a prize. Given that this is a scatter-pay product, there are no paylines, and it only awards wins when eight or ten matching images materialize in view on the same spin. 

To begin testing your luck on this slot, you must set your desired bet size using the plus and minus buttons left of the central spin functions. The wagering range here starts at $0.10 and ends at a somewhat underwhelming $6. After you have settled on how much you wish to stake in a game round, press the right-pointing arrow to get Money Train 4’s reels to turn. You can automate your session setting from ten to an infinite number of automated reel rotations.

Respins in Money Train 4 may activate on any spin, with the token most present becoming a sticky one, and other instances of it can again land. It is also possible to hit multipliers that give an extra spin and are added together at the end of this feature.

That said, the Money Cart Bonus is what makes this slot unique, and it is triggered by at least three Bonus symbols, but know that gold tokens can substitute these for round activation. The round provides three spins, and it resets when new bonus/scatter symbols hit and activating tokens reveal multipliers (up to x10). Landed symbols become locked, and each time you pack a row with them, you open a new one, growing the game layout to a size of 6x8 since this feature begins with a 6x4 grid. Loads of special symbols come into this mode, each performing a distinct action. This is what this game is most famous for. 

You can buy your way into the Money Cart Bonus for 100x or 500x if you want to trigger it with a persistent symbol active.

The Money Train 4 slot’s RTP is 96.10%. Its volatility is high, and the highest win it can generate is a reward of 150,000x.

Does Money Train 4 meet expectations? We say yes. It builds on the foundations laid by its predecessors and enhances them with better visuals and slight gameplay tweaks. Is this the best Money Train slot? That is up for debate, as the last three Relax Gaming installments have all been spectacular. But we believe this entry has buckets of charm, over twenty features, and supplies a memorable train ride through a fictitious Wild West that no one who plays this video slot will ever forget.
